This originates from the basic structure of the human brain.
In the first place, the ``mind'' that we are always conscious of is part of the brain's functions.
History of brain evolution
Over millions of years of evolutionary history, the brain has developed in an incremental manner.
Broadly speaking, the brain evolved in the following order: brain stem (life-sustaining functions), limbic system (emotional functions), and neocortex (thinking functions).
In this way, emotional brains existed hundreds of years before thinking brains were born.
Therefore, the brain with emotional functions has countless circuits connecting it to the brain with thinking functions.
Because of this neural circuit structure, emotions have an extremely strong influence and decision-making power over the functioning of the entire brain.
Normally, our brains have two parts: a brain with emotional functions and a brain with thinking functions, and we think and act rationally while maintaining a balance between the two.
However, when strong emotions arise, such as when an emergency occurs, the balance between the two is disrupted.
Due to the structure of the brain's neural circuits mentioned earlier, the brain with emotional functions overwhelms all other brain functions. Therefore, the emotional side reacts a little faster than the intellect.
Emotional reactions that often go wrong
The amygdala nucleus is responsible for this faster response.
The amygdala nucleus is located in the emotional brain and stores memories associated with emotions. When strong emotions arise, such as when an emergency occurs, we compare the events in front of us one by one with cases that have occurred in the past.
However, if there is even a slight coincidence with a similar case that has only a small part in common, we will quickly conclude that this is the case based on the thoughts, emotions, and reactions that are etched in our minds.
It is said that we often make mistakes because we react before fully checking.
It is said that this is based on the reactions that occur shortly after birth, and there is also the idea that events in early childhood have an influence on later thinking.
Normally, the brain, which has thinking functions, analyzes and recognizes information through multiple layers of neural circuits, and responds rationally (generally considered to be correct).
summary
From these functions of the brain (mind), we can understand how important the balance between emotion and intellect is in our lives.
You'll find hints on how to live a vibrant life, including relationships, work, health, and self-growth.
Isn't it also important to improve your so-called ``emotional intelligence,'' such as being aware of your own emotions, controlling them, persevering without giving up even when you fail, and being considerate of the feelings of others?
